![]() It might be overkill. I would gradually work you way up to that much. I think its possible but i think you should play on the safe size. How deep is tank and what are you keeping for corals?

![]() My tank is about 20" tall and the T5's are currently about 4-5" above that and the metal halides are 7-8" above. When I build the canopy this week all the lights positions will be reversed.
If you guys recommend having them higher I need to know tonight because tomarrow I start cutting ![]() In my tank I have cabbage coral, pulsing xenia, frog spawn, mushrooms, candy cane coral, zoas, flower pots, kenya tree, GSP, toad stools. I also have a clam. All of the low light stuff is near bottom and off to the sides. All the higher light stuff is center and positioned higher. |

![]() i wouldnt move them higher unless they are in risk of being splashed by salt water. I just think you should build up to that long of a photoperiod. My only concern is the duration not the intensity. Can't you feed the fish when you get home and not have the actinics come on so early? I find the fish eat better later in the day anyways.

![]() I will gradually work the intensity up and I can certainly feed the fish in the evening. To reduce the duration what time should I move the atinics on to?
Also I should note that when its time for my next bulb change I am considering changing all the T5's to different daytime colors without atinics. I will still have 2 65w atinics. Last edited by Wayne; 09-14-2010 at 02:15 AM. |

![]() here is how mine are, not saying it is right but just to give you an idea. I have 4 sets of 2 bulbs per 4' of tank, so 1st bank comes on at 9, 2nd at 10, 3rd at 11 and 4th at 12. Then shut off in reverse starting at 6 pm.

![]() I could do something similar with the atinics on, 2 T5's, 2 T5's, Metal halides and then reverse. Better simulation of ocean brightness. I like that idea.
